;Be it known ythat I, PAUL G. HoLLs'TnIN, a subject of the German Emperor, and Ya resident of Carlstadt, in the county of Bergen and State of' New Jersey, -have invented anew and Improved Powdered-Cocoa lFluffer, Mixer, and Cooler, of 4which the `following-is a full, clear, and exact description.

`My Invention relates to a new andimproved zform' of cocoa lulfer, kneader and cooler, and an object of my invention `is.to pulverized cocoa is fed after the cocoa-butter oil isex- Etraeted, and the cocoasubjected to a cooling, I g and aerating process as`v `1t isslowly passed through the same.

Smoothing, nunin "I attain the above outlined object by positioninga number of superimposed pans, in each of which pans are revolving arms, said arms acting-in succession on `the cocoa, `to cool, stir up, Huff, mix and knead thev particles of cocoa, after which they are forced through openings in the bottom of one' pan to the next succeeding lower pan where the same operation is repeated, vand so on until the last pan is reached, when the cocoa is Reference is 15o balad to the accompany ing drawings, forming-a part ofvthis specli similar characters ofi-efer-y gparts infallthecation, in which figures, and in `whichtransverse sectional view ofthe up rltwo 'of Figi 3 and Vlooking in the direction of the arrow; `Fig.`3is a plan viewilookingdo'wn upon-the top pan; and Fig. 4is a diagram.-

shown to be a worm cylinder 7 vrigidly mounted upon a suitable power shaft 8,

which' shaft is mounted in journal's`9 and 10.'

Concentrically disposed relative to `said shaft 8 are a series of shallow `pans 11,.one disposed above the other and supported in position by means of standards` 12, in fthis instance shown to be four T bars spaced ninety degrees apart with the longitudinal center of fthe shaft. as the apex of the angle. It will be noted-from the above outlined construction that a free air space '13`is formed between succeeding pans.

` Rigidly attached to the center ofthe bot- Atom 14 of each of the lpans ands'urrounding @the shaft 5, is a sleeve 15.` Rotatably ed upon each -of the sleeves l'and suitably- .mountkeyed to the shaft, isa sleeve 16, which sleeve, lin this instance, has four arms' 17 -radiating therefrom and at ninety degrees to each other. Rigidly carried by each ofi the arms 17, is the-short arm 18 of an'L shaped rodf1'9, the long arm20 of said L- shaped rod extending W Afroma diameterpassing throughsaid shaft. Pivotally mounted 'upon the 'long arn 20 of the jrod v19, is a` pair of 4spaced-apart straps21 and 22, which strapsare fastened by means of rivets 23, to the back of a 'forwardly and downwardly-inclined plate 24, as shown more particularly in Fig. 3, bein the rota-tin rod 19, in this 'se. The outer a flexible scoop? 26 tilted slightly upward.

Theplates 211 are limited in their inward movement fby a 'suitable -stop ring 27 -ad v justably positioned on-vthe flong Yarm'20 of 90 the rod'19, asv shown more particularly lin Fig.` 2. f '.Further, the lower end voftheplates 24 opposite vthe scoop'26, is 'formed into a reduced extension'28, in o'f which parallel 'to and oii'set inclined in the direction of 7 plates this extension terminates at thev inter- 95 section of its lower edge 29 -and altangent -to'the sleeve 16. 'Oneof the plates 24, yhereinafter referred to asthe scraper 24" has a curved scraper plate 30 Yriveted to the ex-` tension 28 and engaging the sleeve 15. This scraper 24 'bears on the bottom of the pan 11 and collects all ofthe powdered cocoa, permitting'the 'same to fall through openings 31 and 32 in the bottom of the plate into position on the bottom of the next suc ceeding plate, just in advance of the similarly constructed openings 31 and 32 in this next succeeding lower plate. All of the plates 24, with the exception of the scraper 24', have their lower edges positioned sucl cessfully higher distances from the scraper 24', counting in the direction of movement and as shown more particularly in Fig. 4. The four plates 24- of the top pan are unperforated as is also the scraper plate of each of the succeeding pans, but allof the other plates have a horizontal series of apertures 33 extending therethrough, which apertures,

. as shown in Fig. 2, extend through the plate just above the lower edge, and also extend through the scoop 26. As shown in dot-ted lines in Fig. 3, each-set of plates in the succeedlng pans counting from the bottom, is positioned a slight angular distance in advance of the plates in the pan just below, so that the scraper of the pan next above will dump the powdered cocoa on to the pan next below, just in advance of the plate 24 which is positioned the highest distance from the bottom of this pan.

1 It will be seen by the above outlined construction, that after the cocoa is fed by any suitable means into the upper pan, yit is smoothed and leveled by means of the unperforated plates in said upper pan, and

is then forced through the openings 'ini the bottom ofthe pan into the next adjacent pan where it is acted upon in successive layers. bythe perforated plates 24, causing a'flufvfing, kneading and loosening, as well as a coollng actlon on the pulverized particles.l

of cocoa, and this combined action is repeated inthe succeeding pans over as long I a cycle as desired. s

It will be notedthat the pans are comparatively shallow and that as the particles of cocoa are fed from one pany to the next,

they aresubjected to the air in the space 13,`the reby aerating the cocoa,l after which the, cocoa iswithdrawn into a-suitable receptacle and boxed.
